This study focused on smartphone adoption of foreign students who are studying in Korea in digital media era. Smartphone is not only new media but also social media. Based on former research, factor for smartphone adoption of foreign students will be analyzed. Based on TAM theory technological attribute, individual attribute and social attribute were taken out as independent variables. Perceived ease of use and perceived usefulness are applied as mediator variables. In conclusion, some hypotheses for example service quality and individual attribute are rejected as variables which influence positively to mediator variable perceived easy of use. For the next research more various variables and nationwide sampling will be needed.

The crustal deformation due to Ocean Tide Loading (OTL) in the Korean peninsula reaches up to ${\sim}3cm$ in the vertical direction. Considering that the achievable positioning accuracy of current state-of-the-art space geodesy technologies is at the several millimeter level, the centimeter-level OTL effect should be precisely modelled and corrected for. This study begins with comparison of ocean tide models and validation of OTL-prediction softwares. Different ocean tide models caused about ${\sim}6mm$ RMS differences in the vertical deformation in the Kyung-gi Bay area. When we analyzed the OTL displacements in the Seoul, Ulsan, and Seogwipo areas where three VLBI observatories are planned to be installed, the maximum displacement of ${\sim}3.5cm$ was predicted in the Seogwipo area and ${\sim}2cm$ in the Seoul and Ulsan areas. When the OTL corrections were not applied in the GPS data processing, the OTL effect propagates into the Zenith Wet Delay (ZWD) estimates, and the scale factor between ZWD differences and OTL displacements was 3.72.

Given the current situation that there are a lot of rapid change in retail environment and have to offer more customized services to consumers, it is possible for Super Supermarket(SSM hereinafter) to get those. Thus it is explored whether perceived quality affected the customer satisfaction and in turn, the customer satisfaction affected the repurchase intention in SSMs. Especially we investigated the moderate effect of income, age, the number of family members on the relationship between customer satisfaction and repurchase intention. We used the method of structural equation modeling to test hypotheses. As a result, 5 out of 7 hypotheses are statistically significant and partially supported in moderate effects. The results of this study imply that mangers in SSMs have to improve those positive factors that were revealed significant. And given the fact that main customers in SSMs are those who live near and is a nuclear family, they should offer high quality goods and services relevant to them.

In recent years, the retail industry has been undergoing major shifts. Outlet malls are an important part of the new retail landscape. This paper seeks to increase the understanding of the shopping experiences of visitors to a Premium outlet shopping mall in Shinsagae Chelsea Premium Outlet at Paju City, Gyeongi-do. This paper analyze the Element of the premium outlet across demographics. It explores seven critical factors which significantly influence customers' perceptions of premium outlet. Findings are base on a mall intercept survey with 292 respondents across a range of demographics. The summary of 7 factor is classified as the visual, location, Shopping support, human traces, mood, transit expedience, and tenant. The main implication of these findings is that factory outlet stores are perceived favourably and that they need to build more positive marketing strategies accordingly.

구강점막 각 부위의 지각신경의 특징은 근년 생리학적 연구의 중요한 대상이 되어왔다. 일반적으로 생리학적 기능은 연령과 더불어 감소된다는 소견이 구강점막에서도 적용된다고 하나 이에대한 형태학적 지견을 중심으로 볼 때 그러한 감소가 순전한 기능저하의 결과인지 혹은 지각신경의 해부학적 형태변화에 의한 것인지에 대해서는 분명하게 알려진 것이 없다. 본 논문은 Spraque-Dawely와 Fischer 344 두종의 숫자 20마리를 이용하여 각종을 6개월과 30개월의 연령으로 2군으로 나누어서 연령에 따른 구강점막내 신경섬유와 신경종말의 전자현미경적 특성의 변환을 관찰하고, 단위면적당 분포하고 있는 신경요소의 변화를 정량해 보았던바 다음과 같은 결과를 얻었다. 1. 구강점막에 분포하는 신경섬유와 신경종말의 전자현미경적 형태에 있어서는 젊은백서와 늙은백서 사이에 인정할 만한 질적 차이가 없었다. 2. 연령증가에 따라 구강점막의 상피내 간격에 존재하는 신경요소는 전반적으로 감소하였다. 3. 이와 같은 감소는 신경섬유보다 신경종말의 경우 더욱 현저하게 나타났다.

This study explored the heterogeneous latent group on the influence of the learner's perceived math teaching method(instructor-centered, learner-centered) on math self-efficacy. In order to profile the characteristics of the detected latent group, the distribution of variables was confirmed, and multi-group analysis was conducted by SEM. According to the analysis results, two latent groups were detected, and the instructor-type group and the learner-type group were named. As a result of post-hoc analysis, the perception of instructor-centered classes and learner-centered classes, and the perception of math teaching ability were similar between the instructor-type and the learner-type group. But the instructor-type group had higher math self-efficacy, math interest, and math class engagement than the learner-type group. Also, in the instructor-type group, the effect of perception of math teaching ability on math self-efficacy and math class engagement was greater than that of the learner-type group. Whereas, in the learner-type group, the effect of math interest on math self-efficacy and math class engagement was greater than that of the instructor-type group. This study presented a new research method on the influence of math teaching methods on learners by applying the REBUS-PLS method.

The musical interval tells how two different pitches are related to each other. In this paper, 2 experiments examined the existence of a culture-specific system in the perception of musical intervals. These experiments evaluated the discrimination performance by the western-music experts and non-experts. The observed results demonstrate a quite different pattern compared to that of the western-culture. In these experiments. the perfect fourth's perceptual stability was clearly shown. This is significant in terms of the musical-processing system that reflects the culture-specific emotion in the domain of music. Even though we are widely exposed by the Western-tonal music. it is assumed that we have a certain type of gravity within our own musical pitch system. It has suggested that, for an advanced research, we need to carry out the tasks, requiring more empirical data independently from that of the western listeners.

The purpose of this study is to investigate the influences of transaction information and reputation about alliance partner on opportunism and alliance performance. In this study, a structural model and several hypotheses were developed regarding the relationships between transaction term, transaction records, reputation of alliance partner, opportunism, and alliance performance. Based on the collected data, the structural model was analyzed with Lisrel 8.12. The results can be summarized as follows. First, the longer the transaction term, the lower the opportunism and the higher the perceived alliance performances. Second, the better the transaction records, the lower the opportunism and the higher the perceived alliance performances. Third, the reputation of alliance partner company has not any influence on the opportunism and the perceived alliance performances. Finally, the lower the opportunism of alliance partner, the higher the perceived alliance performances. At the end of the paper, managerial implications and future research directions are discussed.
